Rays of light entering the eye are brought to a precise focus on the retina – the light sensitive layer lining the back of the eye. When such a focus is not achieved, a refractive error results and vision is not clear. These imperfections in the focusing power of the eye are called refractive errors. Some people are born with refractive errors and some develop these refractive errors over time. The various reasons that cause changes in the refractive ability of the eye include the ageing process, physiological changes in body, stress, individual lifestyle like working on digital devices for long periods etc. Poor quality of vision can disturb day to day activities and therefore eye tests done at regular periods can help address this issue. An eye test helps determine the type of refractive error occurring in the eye and the means to correct the same.Steps involved in an eye test:
